DeepMind's AlphaProof Code verifies Signal protocol in four-week proof-of-concept

#deepmind#signal#formal verification#lean

Google DeepMind researchers used the agentic AI framework AlphaProof Code to formally verify the cryptographic guarantees of the Signal protocol in a four-week proof-of-concept. The agents wrote three million lines of proofs in Lean to verify Signal's core encryption, marking a breakthrough in verifying complex software at depth.

  • Anthropic open-sources FlashProve for cryptographic verification of AI model identity

    Anthropic released FlashProve, an open-source prototype that uses zero-knowledge cryptography to verify that an AI response came from a specific model, preventing routers or providers from swapping in cheaper models. Tested on a 400B-parameter mixture-of-experts model, it generates proofs at about 110 tokens per second on a single NVIDIA H100 GPU, with proof files around 19 MB per 1024-token request. The release includes proof generators, C++ and Lean verifiers, documentation, and formal proofs.
